Specification of Letters Eatent.

Patented June l, 1909.

Application filed October 12, 1906. Serial No. 338,568.

r 70 all whom it 'may concern.'

it known that l, Env/Ann FAUFMANN, a citizen of the United States, and a resident ot the city of St. Louis and State ol" Missouri, have invented a new and useful improvement in Bushings, of which the following is a specification.

My invention relates to brings for barrels, lregs and the like, and has for its principal objects to provide a simple and efficient device adapted to retain a revenue stamp or label in place over the bung to provide a bung bushing with means constituting a p art oi the stamp retaining device and adapted to facilitate the proper positioning` ot a tapping device; and to attain certain `other advantages hereinatter more fully appearing.

The invention consists in the parts and in the arrangements and combinations of parts hereinafter described and claimed.

ln the accompanying drawings, which form part of this specification and wherein like symbols refer to like parts wherever they occur, Figure 1 is a fragmentary view oi a portion of a barrel head showing a representation ot a revenue stamp or label atlixed over the bung, and the securing device in position; Fig. 2 is a section taken on the line 2 2 of Fig. l Fig. 3 is a detail view of a preferred form of securing strip; Fig. l is a View showing the manner in which the holding means on the bung bushing is adapted to cooperate with the casing of a beer tap, to prevent rotation thereof, and, Fig. 5 is a bottom view of said casing showing the arrangement ot shoulders.

My invention comprises an externally screw-threaded bung bushing l which is slightly tapered and provided with an oxternal annular shoulder 2. rl`his bushing is adapted to be inserted in a counter-sunk bung or tap hole in a barrel head 3, so that the outer end ot the bushing will be flush with the outer tace ot said head. The bushing is counterbored to torni an internal annular shoulder el at its outer end which is adapted to be engaged by the locking members of a beer-tap, such for instance as that shown in U. S. Letters Patent No. 808,341, granted to Manley J. Chaplin on December 26, 1905. On the outer end of the bushing l are lugs 5. These lugs are provided with notches 6 or grooves close to the bushing. A flexible, and

ret'erably resilient plate or strip 7, having rey slots 8 therein near its ends, is adapted to be interlocked with said lugs 5.

in practice, after the stopper Q has been forced into the bushing as shown in Fig. 2, the stamp or label l0 is pasted over the stop- The stam) being easily punctur \d by gs 5, can be made to lie 'flat against the head ot the barrel. The plate 7 is then placed in position above. the stamp and lies against it. yl`hus, ii the paste should not adhere to the barrel, or it the st-amp should become loosened therefrom in any manner, it will still be held in place by the lugs 5 and plate 7, until the plate is intentionally removed. rl"he llate 7 can he conveniently and quickly applied by 'first placing the slotted portion at one end in engagement with one ot 'the lugs 5 and then bending or buckling the plate, as shown in dotted lines in Fig. 2, until the slot at the otner end can be passed over the opposite lug 5, whereupon the plate is pressed or sprung into the position shown in full lines in Figs. l and 2.

The plate 7 may be made of sheet metal, or any other suitable material, such as heavy oiled card board, may be employed to advantage. lt is desirable that a material beused which can be readily removed, yet which possesses the necessary strength and quality of resisting the action of moisture. lt is obvious that instead of forming the key slots S in the plate 7, said plate can be biturcated or notched at its ends, and in other respects changed without in the least departing from the nature and spirit of the invention. Also, instead of providing the notches 6 at the sides of the lugs 5, grooves may be provided in the opposing faces ot the lugs. Furthermore, instead of arranging said lugs at points diametrically opposite, as shown in the drawings, a plurality of lugs may be provided and diiiierently arranged within the scope of the invention.

in attaching a tapping device to a bung bushing, especially a beer tap of the type disclosed in the Chaplin patent hereinbeforc referred to, the casing must be held against turning while the locking is being effected, to insure a tight connection and to prevent undue wear of the packing ring or gasket. By providing shoulders 11 on the casing l2 the lugs 5 may be made to engage therewith when the tap is properly positioned so that its locking members can engage the internal annular shoulder l of the bushing. Thus the lugs can be made to facilitate the proper oy sitioning of the tap priorto locking, as wel as i preventing rotation ol the casing l2 and the sides pecking' ring` 13 when the csp piece i4 is turned to effect the locking' of the ports. The shoulders l] on the casing l2 may be provided by cutting notches shown in Figs. e and 5, or otherwise formed :is desired,

slllutt l claim :is new end desire to securel by Letters Patent is:

l. ji device for retaining revenue stamps on barrels comprising spaced lugs mounted et oft ie bung hole and o plete adapted to be i ioiebly interloclied with seid lugs, seid olmo being' resilient so tl et it may be sprungl into place over the stel-mp.

if?. i device for retaining revenue stamps on barrels comprisingl spaced undercut lugs end e slotted plete adapted to be delechsbly interloclied with seid undercut lugs.

3. A device for retaining revenue stamps on barrels comprising,l spaced undercut lugs inoun ed :it the sides of the bung hole end i slotted plete adapted to be detechebly interloclied 1with seid unoercut lugs, seid plete bcing resilient so that it may be sprung into place. A A bung' bushing having lugs projecting iongitudinztlly beyond the end thereof, said lugs beingl adepte/d to cooperate with e beer tap and constitute ineens lor copereling with i stamp retaining member.

5. A bushing having' longitudinally projecting undercut lugs arrangedv substantially as and for the purpose specified.

i3. A device for retaining revenue stamps i on barrels comprising` a, bung bushing edaptl ed to cooperate with the stopper and having spaced longitudinally proj ectingl undercut lugs thereon, and a stamp retaining member adapted to be detachably interlocked with seid undercut lugs.

7. A device for retaining revenue stamps on barrels comprising` a bungl bushing adapted to cooperate with e stopper and having spaced longitudinally projecting lugs thereon, end :i resilient stamp retainingI member adapted to be detachebly interlocled With seid lugs, seid memberbeing resilient so that it may be sprung into place.

8. The combination With a barrelhaving a tsp hole of :L bushing in said tap hole, said bushing being adapted to receive a stopper :nid interlock With e tap and having lugs there on adapted to facilitate the proper positioning of seid tsp relative thereto, and e stomp retaining member adapted to interlock with said lugs.

ln testimony whereof, l have signed my neme to this specification in the presence of two subscribing Witnesses this 8th dey of October, 1906, et St. Louis, Missouri.
